Hard brick which cannot be unbricked by following forum tutorials. - G2 Q&A, Help & Troubleshooting

Hi, I spotted a big problem today.
After getting installed my cloudy g2 with dorimanx kernel and some tweaks I decided to reflash those in cause of that I thought I regret installing one of the mods which I prepared to install before. I made factory reset and installed stuff, after this my phone boot loops, no entering recovery mode and also fast boot mode is starting with those white titles, not normally. I mean that is showing Fastboot mode started etc.
The biggest problem is that my computer is ain't recognizing my phone in device manager and also in disk manager I can't see this disk with many partitions. Because of that all two tutorials which were made for getting out of that brick, I mean no recovery, no download mode demanding to get device in disk manager or see this device in device manager as qualcomm or qhsusb_bulk I can't do nothing.
Also they want to get some of files included into stock firmware depending on that which version I had before brick, there is next problem because I had cloudy.
I would be grateful if someone can help me, thanks in advance.

GT540 unusual bricked

Well I know you are tired of this kind of threads but this is really strange. Im going to tell the thigs Ive done and hope to resolve this.
Last week I bought this phone and update android from 1.6 to 2.1 successfully and rooted. Used for a day and realised that the phone memory was low because of the apps and games Ive installed so I decided to use app2sd. Completed all the steps and selected Full app2sd and after a few hours noticed that the apps run slow because of the sd speed so I tried to run again app2sd and selected Basic app2sd (without removing, maybe that was the big mistake).
After that my phone is stucked in android loading screen. I can accses to download mode and tried differents ways of reflashing but nothing works (I noticed when flashing with KDZ that the phone reset after the KDZ show FINISHED) and sometimes the "conect to pc animation" apeared or lg screen stuck. Now im trying in XP instead of 7.
Hope you can help me, I can upload pics if you need.
Thanks.
540 Bricked
Hi
I have the same problem (phone stuck in loop at android logo afters app2
sd ) only think worked was flashing it with one of ROMs with Fastboot and recovering image in fastboot mode (in my case I need to install phone again on my PC when in Fastboot mode diffrent drivers) PM me if you have problems gathering things to do that.
PEACE
Hi, I dont know why, maybe because Im new I think I cant send PM. Have you got MSN, skype or something so we can talk?
Thanks
Well to resolve this what Ive did was using the 2.1 Black quarx rom with recovery, so after install booted with fastboot and installed the black screen drivers after that open flash.cmd and the phone boot with the rom.

LG G2 D805 Hard-Bricked. Solutions?

So I'm an argentinian guy that had just bought a LG D-805 device and was so in love with his phone that now, I'm desesperated.
I installed CM 12.1 (NIGHTLY) a few days ago, didn't like it, so downloaded a ROM of "OFFICIAL" 4.4.2 Android for my LG device.
Couldn't install it properly, so I tried re-installing CM 12.1 form my custom recovery (The Win Recovery project v2.7.0).
It seemed to have been installed successfully, as the recovery software was telling me "CM 12.1 was successfully installed".
Then, without giving recovery permissions to root my phone, i tapped on "Reboot System".
What happened next is something unknown for me.
I'm not able to enter recovery mode, emergency (download) mode, fastboot mode, etc. and the screen doesn't even turn on ('cause sometimes it's on but not showing anithing, but in this case, it´s not turning on).
I did research and found out something about QUALCOMM QHSUSB_BULK. What I found out was that, if my PC detects many disks from an unknown device, I could execute some CMD files to get download mode back and if I had download mode back, I could re-install Android.
As I am not a lucky person, my PC detects the qhsusb_bulk device, but does NOT show any disk or partition; it does NOT ask me for formatting anything. I tried installing QUALCOMM DRIVERS, but it's still the same.
I start to think it's a motherboard problem, that I'll have to replace it, but don't know if there is another easier (and cheaper) way to have my phone back.
Any suggestions?

AT&T D800 bricked? Secure boot error, no download mode or recovery

Alright so here's what happened. Last night I decided to update to the latest Cyanogenmod nightly. Turns out that was a bad idea, because it blackscreened on me. Ok, so I flashed the stock firmware, it was working. I decide to reinstall TWRP back on it. It didn't seem to take so I just said "**** it" and went to sleep. I wake up the next morning and what do I see? "Secure booting error Error: Boot Certification Verify!" No download mode, no recovery. So alright, I've followed the guide here: http://forum.xda-developers.com/showthread.php?t=2582142 but I hit a roadblock. Now this is where things become weirder. When I plug my phone in to USB in its current state, it's kind of hard to explain, but here's what it does: The backlight flashes on and off constantly. In Windows (currently in Linux right now as per the guide) it acted as if it kept trying to mount itself. Windows didn't like this at all because apparently it was doing it constantly, and bringing up a lot of dialog windows with multiple drive letters telling me to format it. Now I suspect the problem has carried over to Linux as well, meaning I can't push the images I need to to my phone in order to fix it, since it won't mount itself properly. Yes, I even tried disabling automount like the guide suggested and that didn't help. I'm guessing it's a bootloop issue? I dunno. I'm completely stuck, frustrated, and I really hope I don't have to buy a new phone. Any suggestions? I really need help with this. Thanks.
The long list of tons of drives (and no Download mode) is fairly easy to fix thanks to the solution at:
http://forum.xda-developers.com/lg-g...6#post56739916
To simplify, just download his premade package for the D800 (he lists other versions in the description of his YouTube video) at https://mega.nz/#!mN0SkDpb!1R36L-F05...88X5OuIqwNdezM
and also download and install the Qualcomm drivers from here:
http://www.mediafire.com/download/pb...SB+Drivers.rar
In the instructions he shows Computer Management, a Windows tool. If you are unfamiliar, you can find it under Control Panel -> System and Security -> Administrative tools (click on it)

Hi, you've a SECURITY ERROR, it happened also to me, so don't worry. Maybe you've flashed something not fully compatible with your bootstack, or flashing procedure gave a error. Anyway, try to follow these steps:

Black screen, no DL mode, no boot, just a brick - device without root

Hello guys!
Unfortunately I have managed to full brick my phone which has worked without any issues for more then 3 years.
My story:
1. Phone started to have random restarts, basicaly, when phone lagged little bit - it restarted phone.
2. When I did manual restart, I got into bootloop and could not get out
3. With a heavy heart I did a factory reset. - Problem with random restarts ontinued together with random bootloops.
4. Did maybe 5 more factory resets, nothing happened.
5. Found a tutorial to flash new firmware.I was on 5.0.2 D802 30d so I used same. (PC suite could not find my phone and LG support tool always freezed on SW install)
6. I used LG Flash tool with normal flash. - used *.kdz which I have downloaded via LG support tool - checked size with dl from source from xda and they were same so i used it.)
7. All success, but device keep restarting - i think no bootloop anymore.
8. I did full flash again with LG flash tool so have a clean install and hopefully fix everything.
9. Suddenly mid-install my phone auto-disconnected from laptop and even with Retry attemps I wasnt able to get it running again. Then my phone restarted itself and that was it.
Now I cannot go to recovery mode, I cannot go to Download mode, all I see is black screen (turns some light on little bit underneath but no data visible).
Also when connect to my Windows 10 laptop multiple discs trying to load and trying to format disk. (one of them contains folder image with some files inside).
I dont have root, I dont have any other tools installed on my phone, just a normal user.
I tried to download adb but i dont understand it much, and also it cannot find my device.
Is there any way how to still fix my phone or is it completely lost
If so, I please you for a dummies step-by-step list .
Thank you so much in advance. :crying:
So good news,
I managed to load img back with dd application.
My Download mode together with factory reset is working.
I have tried to flash it with LGUP and even with some accused usb disconnections I probably managed to flash new lollipop to my phone.
Now it is optimalizing apps to load android correctly. Only issue I have is low battery, it always drains it too quickly so it cannot load properly.
Any idea how to charge the battery? Every time I connect phone with usb cable it starts up into boot, possible bootloop (cannot say if it is because of low battery or real bootloop)
Thanks
Dude try to install crdroid 7.1.2 nougat rom of d802 this will fix your battery problem
root it and install TWRP with srktools 2.0
this is best way to root G2 5.0.1 lolipop
you can also use LG One Click Root to obtain root then don't update su binary and install Autorec of you model to get twrp
